BACKGROUND

The integrity of the genome of eukaryotic cells is secured by complex signalling pathways, known as DNA damage response (DDR). Recognition of DNA damage activates DDR pathways resulting in cell cycle arrest, suppression of general translation, induction of DNA repair, and, finally, in cell survival or cell death. Proteins that directly recognize aberrant DNA structures recruit and activate kinases of the DDR pathway, such as ATR. ATR responds to a broad spectrum of DNA damage, including double-strand breaks and lesions derived from interference with DNA replication as well as increased replication stress that is observed in oncogene-driven tumor cells (e.g. Ras mutation/upregulation, Myc upregulation, CyclinE overexpression).

ATR kinase inhibitors are specifically or generically disclosed in the following publications: J. Med. Chem. 2013, 56, 2125-2138; Exp. Rev. Mol.

2-[(3R)-3-methylmorpholin-4-yl]-4-(1-methyl-1H-pyrazol-5-yl)-8-(1H-pyrazol-5-yl)-1,7-naphthyridine (in the following called “Compound A”) is a new ATR kinase inhibitor, which together with more than 400 other ATR kinase inhibitors was described in International Patent Application WO2016020320. Identification of one or more biomarkers that predict sensitivity to Compound A could result in more effective biomarker-driven targeted therapy for hyper-proliferative diseases.

No predictive markers for ATR kinase inhibitors have been identified yet in the clinical setting. However, preclinical evidence suggests a number of candidate predictive biomarkers for ATR kinase inhibitors VE-821, VX-970 and AZD6738: Williamson et al. suggest that ATR kinase inhibitors could have potential as single-agent treatments for ARID1A defective cancers (Nature Communications 7:13837|DOI: 10.1038/ncomms13837, (2016)). According to Mohni et al. ATR pathway inhibition is synthetically lethal in VE-821 treated cancer cells with ERCC1 deficiency and loss of the structure-specific endonuclease ERCC1-XPF (ERCC4) is synthetic lethal with ATR pathway inhibitors (Cancer Res. 74, (2014), 2835-2845). Strong synthetic lethal relationships with ATR inhibition was also shown for the following genes: ATRIP, RPA, CHEK1, CLSPN, HUS1, RAD1, RAD17, TIMELESS, and TIPIN (Mohni et al., Cancer Res. 74, (2014), 2835-2845). ATR inhibition by VE-821 also seems to synergize with loss of ERCC1, ATM and XRCC1 (Mohni et al., PLOS ONE|DOI:10.1371/journal.pone.0125482 May 12, 2015; Sultana et al, PLoS One, 8(2). (2013), e57098. doi: 10.1371/journal.pone.0057098). According to Hocke et al. (Oncotarget Vol. 7, No. 6, (2016), 7080-7095) POLD1 deficiency might represent a predictive marker for treatment response towards ATR inhibitors. Flynn et al. (Science 347, (2015), 273-277) suggest that ATR kinase inhibitors may be useful for treatment of ALT-positive cancers. According to the data described by Menezes et al. (Mol. Cancer. Res. 13(1), (2015), 120-129) single-agent ATR inhibitors may have therapeutic utility in the treatment of mantle cell lymphoma with ATM loss-of-function. Middleton et al. (Oncotarget, Vol. 6, No. 32, (2015), 32396-32409) suggest that defects in ATM, BRCA2, XRCC3 and XRCC1 and high DNA-PKcs expression conferred sensitivity to VE-821 monotherapy.

According to Jones et al. (Cancer Research (2017), Author Manuscript Published OnlineFirst on Oct. 16, 2017; DOI: 10.1158/0008-5472.CAN-17-2056) in Synovial sarcoma SS18-SSX1 or SS18-SSX2 fusion proteins induce ATR kinase inhibitor sensitivity. Nieto-Soler et al. (Oncotarget. 2016; 7:58759-58767) suggest that expression of EWS-FLI1 (also called EWSR1-FLI1) or EWS-ERG (also called EWSR1-ERG oncogenic translocations sensitizes non-ES cells to ATR inhibitors.

Remi-Buisson et al. (Cancer Res 77(17), (2017), 4567-4578) describe that APOBEC3A and APOBEC3B overexpression confers susceptibility to ATR kinase inhibitors.

Kwok et al (Lancet 26, 385, Suppl 1, (2015), S58. doi: 10.1016/S0140-6736(15)60373-7; Blood 4; 127(5), (2016), 582-595. doi: 10.1182/blood-2015-05-644872) showed that AZD6738 sensitized TP53- or ATM-defective primary chronic lymphocytic leukemia (CLL) cells to chemotherapy and ibrutinib. Ruiz et al (Mol Cell 62(2), (2016), 307-313, DOI: 10.1016/j.molce1.2016.03.006) reported that deficiency in cdc25A confers resistance to ATR inhibitors.

The object of the present invention is to provide one or more biomarker(s) for the treatment of one or more hyper-proliferative disease(s) with an ATR kinase inhibitor, particularly with Compound A as described herein, in a subject.

The term “functional mutation” as used herein means a mutation of a gene which results in an altered function of the gene, its corresponding RNA or its corresponding protein compared to the function of the respective wildtype gene, corresponding wildtype RNA or corresponding wildtype protein. The term “altered function” as used herein means either reduced or increased function of the gene, its corresponding RNA or its corresponding protein compared to the function of the respective wildtype gene, corresponding wildtype RNA or corresponding wildtype protein. The term “altered function” also includes the complete loss of the function or the gain of a new function of the gene, its corresponding RNA or its corresponding protein compared to the function of the respective wildtype gene, corresponding wildtype RNA or corresponding wildtype protein.

The reference nucleotide sequences of the cDNA's of the respective wildtype genes are described in the attached sequence protocol (SEQ ID Nos 1 to 111). The reference amino acid sequences of the respective wildtype proteins are described in the attached sequence protocol (SEQ ID Nos 112 to 222).

The functional mutation can be a “deleterious mutation” or an “activating mutation”.

The term “deleterious mutation” as used herein means a mutation of a gene which has a deleterious effect on the function of said gene or on the function of its corresponding RNA or its corresponding protein. For example, the deleterious mutation of the gene may result in a reduced gene expression level of said gene, a reduced amount or a reduced activity of the protein corresponding to said gene, or it may result in a nonfunctional gene/protein (“loss-of-function”) compared to the respective wildtype gene/protein. Examples of a deleterious mutation include but are not limited to the following:

The deleterious mutation can be a nonsense mutation, which is a point mutation in the respective gene, resulting in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and nonfunctional protein corresponding to the respective gene.

The deleterious mutation can be a missense mutation, which is a point mutation in the respective gene, resulting in the production either of a nonfunctional protein (complete loss of function) or in a protein with partial loss of function compared to the respective wildtype protein.

The deleterious mutation can also result in a frameshift mutation, which is a genetic mutation in the respective gene caused by insertions or deletions of one or more nucleotides in such gene, wherein the number of nucleotides is not divisible by three, and resulting in a (sometimes truncated) nonfunctional protein corresponding to the respective gene.

The deleterious mutation can also be a large rearrangement mutation, for example a deletion of one or more exons disrupting the reading frame or a critical functional domain of the corresponding protein. Another example for a large rearrangement mutation is a duplication of one or more non-terminal exons disrupting the reading frame or a critical functional domain of the corresponding protein.

The deleterious mutation can also be a splice site mutation, which is a genetic mutation that inserts, deletes or changes a number of nucleotides in the specific site at which splicing takes place during the processing of precursor messenger RNA into mature messenger RNA. Splice site consensus sequences that drive exon recognition are located at the very termini of introns. The deletion of the splicing site results in one or more introns remaining in mature mRNA thereby resulting in the production of a nonfunctional protein corresponding to the respective gene.

The deleterious mutation can also be a copy number variant (CNV), particularly a decrease of the gene copy number (e.g. a homozygous or heterozygous deletion) compared to the normal gene copy number of the respective gene.

The term “activating mutation” as used herein means a mutation of a gene which changes said gene, its corresponding RNA and/or its corresponding protein in such a way, that its effects (e.g. the amount of corresponding RNA/protein, or the protein activity) get stronger compared to the respective wildtype gene/RNA/protein. The term “activating mutation” also includes a mutation of a gene, in which the protein corresponding to said gene gets a new function compared to the function of the corresponding wildtype protein. Examples of activating mutations include but are not limited to the following:

The activating mutation can be a substitution of one amino acid residue by another that confers a new or higher activity upon the protein.

The activating mutation can be a copy number variant (CNV), particularly an increase of the gene copy number compared to the normal gene copy number of the respective gene.

The activating mutation can also be a fusion gene or fusion protein, e.g. occurring as a result of translocation, interstitial deletion or chromosomal inversion.

The term “stratification method” as used herein means the method by which one or more of the functional mutation(s) as defined herein, particularly of the deleterious mutations and the activating mutations, the activation of the ALT pathway and/or the microsatellite instability is (are) determined.

Preferably, the stratification method is an in-vitro method. Examples of stratification methods, which can be used in context with the present inventions, are described infra.

The term “activation of the ALT pathway” as used herein refers to cancer cells which overcome replicative senescence by activating the Alternative Lengthening of Telomeres (ALT) pathway.

The term “microsatellite instability” (“MSI”) as used herein is the expansion or reduction in the length of repetitive DNA sequences (known as microsatellites) in the DNA of a sample, e.g. a tumor sample, compared to normal cells.

MSI testing can detect an abnormal number of microsatellite repeats, which indicates that the cancer may arose from cells with defect mismatch repair genes. A microsatellite is a tract of tandemly repeated (i.e. adjacent) DNA motifs that range in length from one to six nucleotides, and are typically repeated 5-50 times. For example, the sequence TATATATATA is a dinucleotide microsatellite, and GTCGTCGTCGTCGTC is a trinucleotide microsatellite (with A being Adenine, G Guanine, C Cytosine, and T Thymine). Repeat units of four and five nucleotides are referred to as tetra- and pentanucleotide motifs, respectively. Microsatellites are distributed throughout the genome. Many are located in non-coding parts of the human genome, however they can also be located in regulatory regions and within the coding region. MSI tumors may result from inactivating germline mutations in one or more genes, including MLH1, MSH2, MSH6 and PMS2, and epithelial cell adhesion molecule (EPCAM), such as occurs in patients with Lynch syndrome, for whom more than 90% of colon cancers test MSI positive. MSI also occurs sporadically in several cancer types, including colorectal, endometrial, ovarian, and gastric cancers. In contrast to Lynch syndrome, sporadic MSI is often due to somatic promoter hypermethylation of MLH1 in the absence of gene sequence mutations.

The term “sample” as used herein means the sample from the subject, preferably an in vitro sample, which is used in the stratification method (as defined herein), e.g. a sample of tumor cells or of tumor tissue, a blood sample, particularly a sample of tumor tissue containing tumor cells.

In another embodiment the present invention covers a pharmaceutical composition comprising an inhibitor of ATR kinase, particularly Compound A, together with one or more pharmaceutically acceptable excipients for use in any of the method(s)/use(s) for treating a hyper-proliferative disease in a subject described herein.

The inhibitor of ATR kinase, particularly Compound A, can act systemically and/or locally. For this purpose, it can be administered in a suitable manner, for example by the oral, parenteral, pulmonal, nasal, sublingual, lingual, buccal, rectal, dermal, transdermal, conjunctival, otic route, or as an implant or stent. The inhibitor of ATR kinase, particularly Compound A, can be administered in administration forms suitable for these administration routes.

Suitable administration forms for oral administration are those which deliver Compound A in a rapid and/or modified manner, and contain Compound A in crystalline and/or amorphous and/or dissolved form, for example tablets (uncoated or coated tablets, for example with enteric or retarded-dissolution or insoluble coatings which control the release of Compound A, tablets or films/wafers which disintegrate rapidly in the oral cavity, films/lyophilizates, capsules (for example hard or soft gelatin capsules), sugar-coated tablets, granules, pellets, powders, emulsions, suspensions, aerosols or solutions. Parenteral administration can be accomplished with avoidance of an absorption step (for example by an intravenous, intraarterial, intracardial, intraspinal or intralumbal route) or with inclusion of an absorption (for example by an intramuscular, subcutaneous, intracutaneous, percutaneous or intraperitoneal route). Suitable administration forms for parenteral administration include injection and infusion formulations in the form of solutions, suspensions, emulsions, lyophilizates or sterile powders.

For the other administration routes, suitable examples are pharmaceutical forms for inhalation or inhalation medicaments (including powder inhalers, nebulizers), nasal drops, solutions or sprays; tablets, films/wafers or capsules for lingual, sublingual or buccal administration, films/wafers or capsules, suppositories, ear or eye preparations (for example eye baths, ocular insert, ear drops, ear powders, ear-rinses, ear tampons), vaginal capsules, aqueous suspensions (lotions, shaking mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (for example patches), milk, pastes, foams, dusting powders, implants, intrauterine coils, vaginal rings or stents. Compound A can be converted to the administration forms mentioned. This can be done in a manner known per se, by mixing with pharmaceutically suitable excipients.

These excipients include carriers (for example microcrystalline cellulose, lactose, mannitol), solvents (e.g. liquid polyethylene glycols), emulsifiers and dispersing or wetting agents (for example sodium dodecylsulphate, polyoxysorbitan oleate), binders (for example polyvinylpyrrolidone), synthetic and natural polymers (for example albumin), stabilizers (e.g. antioxidants, for example ascorbic acid), dyes (e.g. inorganic pigments, for example iron oxides) and flavour and/or odour correctants.

The present invention further covers the use of pharmaceutical compositions which comprise the inhibitor of ATR kinase, particularly Compound A, together with one or more, preferably inert, nontoxic, pharmaceutically suitable excipients, for use in any of the method(s)/use(s) for treating a hyper-proliferative disease in a subject described herein.

Based upon standard laboratory techniques known to evaluate compounds useful for the treatment of hyper-proliferative diseases by standard toxicity tests and by standard pharmacological assays for the determination of treatment of the conditions identified above in mammals, and by comparison of these results with the results of known active ingredients or medicaments that are used to treat these conditions, the effective dosage of the compounds of this invention can be determined for treatment of each desired indication. The amount of the active ingredient to be administered in the treatment of one of these conditions can vary widely according to such considerations as the particular compound and dosage unit employed, the mode of administration, the period of treatment, the age and sex of the patient treated, and the nature and extent of the condition treated.

The total amount of the active ingredient to be administered will generally range from about 0.001 mg/kg to about 200 mg/kg body weight per day, and preferably from about 0.01 mg/kg to about 50 mg/kg body weight per day. Clinically useful dosing schedules will range from one to three times a day dosing to once every four weeks dosing. In addition, “drug holidays” in which a patient is not dosed with a drug for a certain period of time, may be beneficial to the overall balance between pharmacological effect and tolerability. A unit dosage may contain from about 0.5 mg to about 1500 mg of active ingredient, and can be administered one or more times per day or less than once a day. The average daily dosage for administration by injection, including intravenous, intramuscular, subcutaneous and parenteral injections, and use of infusion techniques will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily rectal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily vaginal dosage regimen will preferably be from 0.01 to 200 mg/kg of total body weight. The average daily topical dosage regimen will preferably be from 0.1 to 200 mg administered between one to four times daily. The transdermal concentration will preferably be that required to maintain a daily dose of from 0.01 to 200 mg/kg. The average daily inhalation dosage regimen will preferably be from 0.01 to 100 mg/kg of total body weight.

Of course the specific initial and continuing dosage regimen for each patient will vary according to the nature and severity of the condition as determined by the attending diagnostician, the activity of the specific compound employed, the age and general condition of the patient, time of administration, route of administration, rate of excretion of the drug, drug combinations, and the like. The desired mode of treatment and number of doses of a compound of the present invention or a pharmaceutically acceptable salt or ester or composition thereof can be ascertained by those skilled in the art using conventional treatment tests.

In spite of this, it may be necessary to deviate from the amounts specified, specifically depending on body weight, administration route, individual behaviour towards the active ingredient, type of formulation, and time or interval of administration. For instance, less than the aforementioned minimum amount may be sufficient in some cases, while the upper limit mentioned has to be exceeded in other cases. In the case of administration of greater amounts, it may be advisable to divide them into several individual doses over the day.

Stratification Methods

Various stratification methods can be used in context of the present invention to identify one or more functional mutation(s) in one or more gene(s), an activation of the ALT pathway and/or microsatellite instability (MSI) in a sample.

Functional Mutation(s)

The determination of functional mutations, particularly of deleterious and activating mutations, of gene(s)/protein(s) is known to the person skilled in the art. Deleterious mutations and activating mutations can be, for example, determined by one or more of the following stratification methods: Next generation sequencing (NGS) (Metzker M L, “Sequencing technologies—the next generation”, Nat Rev Genet. 2010; 11:31-46); Sanger sequencing and other first generation sequencing methods (Lilian T. C. Franca, Emanuel Carrilho and Tarso B. L. Kist, A review of DNA sequencing techniques, Quarterly Reviews of Biophysics 35, 2 (2002), pp. 169-200); PCR, particularly multiplex PCR; Fluorescence in situ hybridization (FISH); array comparative genomic hybridization (array CGH); single nucleotide polymorphism microarray (SNP microarrays), in particular to determine copy number variants (CNVs); or immunohistochemistry (IHC), in particular to determine the loss or overexpression of the respective protein.

The term “NGS” does not denote a single technique; rather, it refers to a diverse collection of post-Sanger sequencing technologies developed in the last decade. These methods include sequencing-by-synthesis (Ronaghi M et al., “A sequencing method based on real-time pyrophosphate”, Science. 1998; 281:363-365), sequencing-by-ligation (Shendure J et al., “Accurate multiplex polony sequencing of an evolved bacterial genome”, Science. 2005; 309:1728-32.16), ion semiconductor sequencing (Rothberg J M et al., “An integrated semiconductor device enabling non-optical genome sequencing.”, Nature. 2011; 475:348-52.17), and others.

Bioinformatics approaches are used for detecting and analyzing the sequence variants from NGS data (Teng S, “NGS for Sequence Variants.”, Adv Exp Med Biol. 2016; 939:1-20). NGS variant detection consists of quality control (to remove potential artifacts and bias from data), sequence alignment (reads are mapped to positions on a reference genome), and variant calling (which is performed by comparing the aligned reads with known reference sequences to find which segments are different with the reference genomes).

The sequence variants detected from NGS can be classified to single nucleotide variants (SNVs), small insertions and deletions (INDELs), and large structural variants (SVs) based on their sequences in length. SNVs, the most common type of sequence variants, are single DNA basepair differences in individuals. INDELs are defined as small DNA polymorphisms including both insertions and deletions ranging from 1 to 50 bp in length. SVs are large genomic alterations (>50 bp) including unbalanced variants (deletions, insertions, or duplications) and balanced changes (translocations and inversions). Copy number variants (CNVs), a large category of unbalanced SVs, are DNA alterations that result in the abnormal number of copies of particular DNA segments.

Variant analysis includes variant annotation which can be used to determine the effects of sequence variants on genes and proteins and filter the functional important variants from a background of neutral polymorphisms.

Variant association analyses connects the functional important variants with complex diseases or clinical traits. The disease-related casual variants can be identified by combining these approaches. Results of these variant analysis are stored in public databases, such as for example COSMIC (the Catalogue Of Somatic Mutations In Cancer, www.cancer.sanger.ac.uk), ClinVar (Landrum M J, Lee J M, Riley G R, et al., “ClinVar: public archive of relationships among sequence variation and human phenotype.”, Nucleic Acids Res. 2014; 42:D980-5), HGMD (Stenson P D, Mort M, Ball E V, et al., “The human gene mutation database: 2008 update.”, Genome Med. 2009; 1:13) or “The Human Variome Project” (http://www.humanvariomeproject.org/), which has curated the gene-/disease-specific databases to collect the sequence variants and genes associated with diseases.

As described above, public data bases, relevant literatures and ongoing evidences associated with the recurrence and function of the gene are used to determine the reportable status of an alteration found from NGS data for the genes of interest. Functional mutations can be classified by any one of the following reportable status: deleterious mutation(s) and activation mutation(s).

Activation of the ALT Pathway

In normal somatic cells, significant telomere shortening leads to p53-dependent senescence or apoptosis (Heaphy and Meeker, J Cell Mol Med. 15(6): 1227-1238 (2011)). Cancer cells rely on telomerase or the alternative lengthening of telomeres (ALT) pathway to overcome replicative mortality. Most neoplastic cells express telomerase to support immortalization and tumor progression. However, approximately 10% to 15% of cancers achieve immortalization via a telomerase-independent mechanism of telomere lengthening, the alternative lengthening of telomeres (ALT) (Cesare A. J., Reddel R. R. Alternative lengthening of telomeres: Models, mechanisms and implications. Nat. Rev. Genet. 2010; 11:319-330.). ALT is a recombination-based mechanism of telomere maintenance characterized by heterogeneous, fluctuating telomere lengths, high levels of telomere sister chromatid exchanges (t-SCEs), abundant extrachromosomal telomeric repeat DNA (ECTR), and a specialized telomeric DNA nuclear structure termed ALT-associated promyelocytic leukemia (PML) bodies (APBs) (Robert L. Dilley, Roger A. Greenberg, ALTernative Telomere Maintenance and Cancer, Trends Cancer. 2015 Oct. 1; 1(2): 145-156). Specific mutational events including recurrent mutations of the Alpha Thalassemia/Mental Retardation Syndrome X-Linked (ATRX) or Death-Domain Associated Protein (DAXX) genes have been reported to influence ALT activation and maintenance (Amorim et al, The Role of ATRX in the Alternative Lengthening of Telomeres (ALT) Phenotype, Genes (Basel). 2016 September; 7(9): 66.). Recent studies have implicated the long-noncoding RNA telomeric repeat-containing RNA (TERRA), nuclear receptors, and RPA in the recombinogenic potential of ALT telomeres. ATR protein kinase, a critical regulator of recombination, recruited by the Replication Protein A might be involved in ALT regulation and become a viable target for treatment of ALT tumors (Flynn, R. L.; Cox, K. E.; Jeitany, M.; Wakimoto, H.; Bryll, A. R.; Ganem, N. J.; Bersani, F.; Pineda, J. R.; Suva, M. L.; Benes, C. H.; et al. Alternative lengthening of telomeres renders cancer cells hypersensitive to ATR inhibitors. Science 2015, 347, 273-277.)

Stratification methods known in the art can be used to identify subjects as having a cancer associated with activation of the ALT pathway (i.e., for identifying a cancer as associated with ALT activation, also referred to herein as an ALT cancer or an ALT+ cancer). For example, detection of maintenance of telomeres in the absence of telomerase activity (Bryan et al., EMBO J., 14:4240-4248 (1995)); detection of a pattern of telomere lengths, e.g., by terminal restriction fragment Southem blots, ranging from very short to extremely long, and with a modal length approximately twice that in comparable telomerase-positive or normal cells (Bryan et al., EMBO J., 14:4240-4248 (1995); Gollahon et al., Oncogene, 17:709-717 (1998)), detection of rapid, unsynchronized changes in telomere length cause telomere length heterogeneity (Mumane et al., EMBO J., 13:4953-4962 (1994)), detection of ALT-associated PML bodies (APBs) (Yeager et al., Cancer Res., 59:4175-4179 (1999)), detection of copying of engineered telomeric tags from one telomere to another (Pickett et al. EMBO J., 28:799-809 (2009)), detection of tandem repeat instability at telomeres and the MS32 minisatellite (Jeyapalan et al., Hum. Mol. Genet., 14: 1785-1794 (2005)), detection of Telomere-sister chromatid exchange (T-SCE) (Fan et al. Nucleic Acids Res., 37:1740-1754 (2009)), detection of an increase in the level of telomeric t-circles (Cesare et al., Mol. Cell. Biol., 24:9948-9957 (2004)), detection of single stranded C-strand telomeric DNA (ss-C-strand) (Grudic et al., Nucleic Acids Res., 35:7267-7278 (2007)), detection of C circles (Henson et al., Nat. Biotechnol., 27:1181-1185 (2009)). See, e.g. Henson and Reddel, FEBS Lett. 584(17):3800-3811 (2010); and US20150247866. In some embodiments, a branched DNA assay in RNA in situ hybridization (RNA-ISH) is used, e.g., as described in WO2015/123565.

The activation of the ALT pathway is preferably determined by one of the stratification methods described above.

Microsatellite Instability (MSI)

MSI analysis involves comparing allelic profiles of microsatellite markers generated by amplification of DNA from matching normal wildtype and test samples, which may be mismatch-repair (MMR) deficient. Alleles that are present in the test sample but not in corresponding normal wildtype samples indicate MSL MSI can be for example analyzed by a MSI-PCR method which includes fluorescently labelled primers for co-amplification of microsatellite markers, by MSI-immunohistochemistry (IHC) staining of four MMR pathway proteins: MLH1, PMS2, MSH2, or MSH6, or by computational methods using next generation DNA sequencing (NGS) data detecting an abnormal number of microsatellite repeats: The term “high microsatellite instability” (herein also called “MSI-high”) means that a significant number, particularly at least one, preferably at least two, of microsatellite markers were found: MSI status can be determined by a MSI-PCR Analysis System (e.g. by Promega Corp, Madison, USA) which is based on the use of five nearly monomorphic mononucleotide microsatellite markers (BAT-25, BAT-26, NR-21, NR-24, and MONO-27). In this system high microsatellite instability (“MSI-high”) is defined as the phenotype, in which at least 2 of the tested microsatellite markers (BAT-25, BAT-26, NR-21, NR-24, and MONO-27) are altered in the sample of the subject compared to a normal reference sample. Low microsatellite instability (“MSI-low”) is defined as the phenotype, in which only one of the tested microsatellite markers is altered in the sample of the subject compared to a normal reference sample. Microsatellite stable (MSS) is defined as the phenotype, in which none of the tested microsatellite markers is altered in the sample of the subject compared to a normal reference sample. MSI status can also be determined by a MSI-PCR method using the five microsatellite loci (BAT-25, BAT-26, D2S123, D5S346, and D175250) recommended by the National Cancer Institute (NCI), which are amplified in a single multiplex PCR reaction. In this system high microsatellite instability (“MSI-high”) is defined as the phenotype, in which at least two of the tested mononucleotide microsatellite markers (BAT-25, BAT-26, D2S123, D5S346, and D175250) are altered in the sample of the subject compared to a normal reference sample. Low microsatellite instability (“MSI-low”) is defined as the phenotype, in which only one of the tested mononucleotide microsatellite markers (BAT-25, BAT-26, D2S123, D5S346, and D175250) is altered in the sample of the subject compared to a normal reference sample. Microsatellite stable (MSS) is defined as the phenotype, in which none of the tested microsatellite markers (BAT-25, BAT-26, D2S123, D5S346, and D175250) is altered in the sample of the subject compared to a normal reference sample (Boland C R, et al, A National Cancer Institute Workshop on Microsatellite Instability for cancer detection and familial predisposition: development of international criteria for the determination of microsatellite instability in colorectal cancer. Cancer Res. 1998; 58(22):5248-5257).

In this context a “normal reference sample” used for MSI testing can be for example a genomic DNA template provided by the assay kit, or DNA isolated from blood or from another non-cancerous tissue from the subject to be tested,

MSI status can be assessed by computational methods to using next generation DNA sequencing (NGS) data generated from tumor or other tissues. These computational methods include but are not limited to mSINGS (Salipante, S. J. et al, “Microsatellite instability detection by next generation sequencing”, Clin. Chem. 60, 1192-1199, 2014), MSISensor (Niu B et al., “MSlsensor: microsatellite instability detection using paired tumor-normal sequence data.”, Bioinformatics. 2014; 30(7):1015-1016.), MANTIS (Microsatellite Analysis for Normal Tumor InStability) (Kautto E A et al, “Performance evaluation for rapid detection of pan-cancer microsatellite instability with MANTIS”, Oncotarget. 2016 Dec. 12), MOSAIC (Ronald J Hause et al, “Classification and characterization of microsatellite instability across 18 cancer types”, Nature Medicine 22, 1342-1350, 2016), or the Foundation Medicine NGS-MSI analysis using 114 intronic homopolymer repeat loci (10-20 bp long in the human reference genome) (Michael J. Hall et al, J Clin Oncol 34, 2016 (suppl 4S; abstr 528).

In these computational methods MSI status can be defined by cutoff numbers for MSI-high, MSI-low or MSS based on an index score for each sample determined by using computer algorithm and validated by comparing to the other MSI detection methods.

MSI can also be detected by an immunohistochemistry (IHC) staining of four microsatellite marker proteins: MLH1, PMS2, MSH2, or MSH6. If any of these four proteins are found significantly reduced in quantity by IHC, particularly if at least one of the four proteins cannot be detected by IHC, the sample is labeled as MSI-high.

In another embodiment of the use/method/pharmaceutical composition/kit of the present invention the microsatellite instability is characterized by the alteration of one or more, preferably of two or more, microsatellite markers selected from BAT-25, BAT-26, NR-21, NR-24, MONO-27, D2S123, D5S346, D175250 in the sample of the subject compared to a normal reference sample and/or microsatellite instability is characterized by the absence of one or more proteins selected from MLH1, PMS2, MSH2 and/or MSH 6.

Treatment of Further Cancer Cell Lines with Compound A

The cells (See Table 3: Test systems) were seeded in their appropriate medium supplemented with 10% FCS at 1,250-5,000 cells/well (depending on their proliferation rate) in 96-well microtiter plates. Cells were allowed to adhere for 24 h, and then the compound was added using a digital dispenser. The final concentration of Compound A was between 1E-09 mol/L and 3E-06 mol/L, and the final concentration of the solvent DMSO was 0.03%. After 4 days of continuous incubation, the cells were fixed with glutaraldehyde, stained with crystal violet, and the absorbance was recorded at 595 nm. All measurements were done in quadruplicates. The values were normalized to the absorbance of solvent treated cells (=100%) and the absorbance of a reference plate which was fixed at the time point of compound application (=0%). Half-maximal growth inhibition (IC₅₀) was determined as compound concentration, which was required to achieve 50% inhibition of cellular growth using a 4-parameter fit. Non-adherent growing GRANTA-519, Jeko-1, JVM-2, NCI-H929, Rec-1 and SU-DHL-8 cells were seeded in 150 μl of growth medium at 4000 cells/well (NCI-H929, 5000 cells/well) in 96-well microtiter plates and incubated for 24 h at 37° C. Compound A was added using a digital dispenser to the cells in the test plates and incubated continuously for 4 days at 37° C. To determine cell viability (corresponding to cell number) CTG solution (Promega Cell Titer Glo solution, # G755B and G756B) was added. After incubation for further 10 min luminescence was measured using Perkin Elmer Victor V equipment. All measurements were done in quadruplicates. The percentage change of cell viability was calculated by normalization with respect to the luminescence reading (cell number) at the beginning of treatment of cells (a reference plate was measured at the time point of compound application to the measurement plates) and the luminescence reading (cell number) of the untreated control group. Half-maximal growth inhibition (IC₅₀) was determined as compound concentration, which was required to achieve 50% inhibition of cellular growth using a 4-parameter fit.

Treatment of Isogenic Cancer Cell Lines with Compound A

The isogenic DLD-1 cell lines DLD-1 parental, DLD-1 BRCA2 (−/−) and DLD-1 ATM (−/−) (see Table 3: Test systems) were seeded in RPMI 1640 (RPMI=Roswell Park Memorial Institute) medium without phenol red+10% charcoal-stripped FCS (FCS=Fetal Calf Serum)+2 mM L-Glutamine+25 mM Sodium Bicarbonate at 2,500 cells/well in a 96-well microtiter plate. Cells were allowed to adhere for 24 h, and then the compound was added using a digital dispenser. The final concentration of Compound A was between 7E-10 mol/L and 5E-06 mol/L, and the final concentration of the solvent DMSO was 0.03%. After 7 days of continuous incubation at 37° C. cell viability was determined (corresponding to cell number) using CTG solution (Promega Cell Titer Glo solution, # G755B and G756B) was added. After incubation for further 10 min luminescence was measured using Perkin Elmer Victor V equipment. All measurements were done in quadruplicates. The percentage change of cell viability was calculated by normalization with respect to the luminescence reading (cell number) at the beginning of treatment of cells (a reference plate was measured at the time point of compound application to the measurement plates) and the luminescence reading (cell number) of the untreated control group. Half-maximal growth inhibition (IC50) was determined as compound concentration, which was required to achieve 50% inhibition of cellular growth using a 4-parameter fit.

Results:

The genetic mutations and DNA copy number alterations of the above-mentioned cancer cell lines were determined by targeted whole exome sequencing testing and/or acquired from the public databases of Cancer Cell Line Encyclopedia (CCLE, Barretina, Caponigro, Stransky et al. The Cancer Cell Line Encyclopedia enables predictive modelling of anticancer drug sensitivity. Nature. 2012 28; 483(7390:603-7.), Genentech Panel (Klijn C, Durinck S, Stawiski E W, Haverty P M, Jiang Z, et al, A comprehensive transcriptional portrait of human cancer cell lines. Nat Biotechnol. 2015 March; 33(3):306-12.) and Sanger Cell Line Panel in COSMIC database (www.cancer.sanger.ac.uk; “COSMIC: exploring the world's knowledge of somatic mutations in human cancer”, Forbes et al., Nucleic Acids Res. 2015, January; 43 (Database issue):D805-11. doi: 10.1093/nar/gku1075. Epub 2014 Oct. 29).

Mutations in DNA damage (DDR) or mismatch repair (MMR) genes as well as mutations in genes inducing oncogenic replication stress or in TP53/tumor suppressor genes of these cancer cell lines (Table 3) are listed in Table 4, selected functional mutations of these cell lines are described in Table 5.

The activity of Compound A in these cell lines was tested. As shown in Table 4, Compound A inhibited the proliferation of the tumor cell lines tested. These results demonstrate that Compound A potently inhibits the proliferation of human tumor cell lines when tested as single agent and that the genetic background of the cells impacts their sensitivity to ATR inhibition.

The activity of Compound A was also tested in isogenic cell lines, in the parental DLD-1 cells and in two DLD-1 cell clones that are deficient for BRCA2 or ATM: DLD-1 BRCA2 (−/−) and DLD-1 ATM (−/−). As shown in Table 6, Compound A inhibited the proliferation of the parental DLD-1 to a lesser extent than the mutant cell lines. The strongest effect was detectable in ATM deficient DLD-1 cells. These results demonstrate that mutations in the genes BRCA2 and ATM sensitize tumor cells to treatment with Compound A.

Example 2 In Vivo Xenotransplantation Models

The anti-tumor activity of of Compound A was examined in murine xenotransplantation models of human cancer. For this purpose, mice were implanted subcutaneously with tumor cells. At a mean tumor size of 20-30 mm² animals were randomized into treatment and control groups (n=10 animals/group) and treatment started with vehicle only or Compound A (formulation: 60% PEG400/10% Ethanol/30% Water; application route: p.o./per os, orally; dose/schedule: 50 mg/kg twice daily for 3 days on/4 days off). The oral application volume was 10 ml/kg. The time interval between two applications per day was 6-7h. The experiment was ended when the untreated control group had tumors of area ≤225 mm². The tumor size and the body weight were determined three times weekly. Changes in the body weight were a measure of treatment-related toxicity (>10%=critical, stop of treatment until recovery, >20%=toxic, termination). The tumor area was detected by means of an electronic caliper gauge [length (mm)×width (mm)]. In vivo anti-tumor efficacy is presented as T/C ratio (Treatment/Control) calculated with tumor areas at study end by the formula [(tumor area of treatment group at day x)−(tumor area of treatment group at day before first treatment)]/[(tumor area of control group at day x)−(tumor area of control group at day before first treatment)]. A compound having a T/C below 0.5 is defined as active (effective). Statistical analysis was assessed using SigmaStat software. A one-way analysis of variance was performed and differences to the control were compared by a pair-wise comparison procedure (Dunn's method).

Results (Table 7):

Compound A showed potent anti-tumor efficacy in different xenograft models of human tumors upon monotherapy treatment inducing stable disease in ovarian (A2780), prostate (PC3), colorectal cancer (LOVO) and complete tumor remission in mantle cell lymphoma (REC-1) at good tolerability.

Example 3 Treatment of Isogenic DT40 Chicken Lymphoma Cell Lines with Compound A

DT40 cells from isogenic cell lines (see Table 8) were seeded in 40 μl of growth medium (RPMI 1640 medium containing stabilized glutamine (# FG1215, Merck/Biochrom), supplemented with 10% fetal calf serum, 1% chicken serum, 100 U/ml penicillin, 100 μg/ml streptomycin, 5E-05M ß-mercaptoethanol) at 200 cells/well in 384-well white microtiter plates ((#6007680; Perkin Elmer Life Sciences) and incubated for 24 h at 37° C. Compound A was added using a digital dispenser (Tecan) to the cells in the test plates and incubated continuously for 3 days at 37° C. To determine cell viability (corresponding to cell number) 10 μl/well of CTG solution (Promega Cell Titer Glo solution, # G755B and G756B) was added. After incubation for further 10 min luminescence was measured using a PHERAstar FSX (BMG Labtech) equipment. All measurements were done in quadruplicates. The percentage change of cell viability was calculated by normalization with respect to the luminescence reading (cell number) at the beginning of treatment of cells (a reference plate was measured at the time point of compound application to the measurement plates) and the luminescence reading (cell number) of the untreated control group. Half-maximal growth inhibition (IC₅₀) was determined as compound concentration, which was required to achieve 50% inhibition of cellular growth using a 4-parameter fit.

To evaluate the relative cellular sensitivity of the isogenic DT40 cell lines towards Compound A the mean IC₅₀ of each mutant cell line was divided by the mean IC₅₀ of wild-type cells, and then the quotient was converted into logarithmic scale (base 2). Loge ratios of ≤−1 or ≥+1, corresponding to a 2-fold change in sensitivity relative to wild-type cells, were considered as particularly relevant.

Results

The activity of Compound A was tested in a panel of 46 isogenic cell lines derived from DT40 chicken lymphoma cells, which do not express TP53 (Takao et al., Oncogene 1999; 18: 7002-7009), covering inactivation of various genes involved in DNA damage signaling and DNA repair. Relative sensitivities against Compound A were calculated for the mutant cell lines versus the parental wild-type cell line (Table 9). The results indicate that cells deficient in the genes TP53BP1, RAD9A, RAD17, H2AFX, RAD52, BRCA1, BRCA2. UBE2N, PCNA, PARP1, TDP2, FANCD2, FANCG, POLL, POLL/POLB double mutated, REV3L, FEN1, XPA, ERCC5, or BLM are 2-fold or more than 2-fold more sensitive towards Compound A as compared to wild-type cells. Strong sensitizations (>4-fold) were observed with RAD17, PARP1, FANCD2, UBE2N, RAD9A, REV3L, TP53BP1, ERCC5, and BLM deficient DT40 cells, whereas the strongest effects (>8-fold) were detectable in PCNA, FEN1, H2AFX, BRCA1 deficient DT40 cells. These results demonstrate that deleterious mutations in the genes TP53BP1, RAD9A, RAD17, H2AFX, RAD52, BRCA1, BRCA2. UBE2N, PCNA, PARP1, TDP2, FANCD2, FANCG, POLL, POLL/POLB double mutated, REV3L, FEN1, XPA, ERCC5, or BLM sensitize tumor cells to treatment with Compound A.
